I'm trying to place an extra header above the title for a specific author. So if "John" posts on the blog, it would have an above the post on the home page that says "John's Perpective", or something of that nature. The idea is that we want one of the many author's posts to be highlighted for users.

My issue is that I cannot figure out how to check for which user wrote the post within the loop. I am doing it on various other areas of the site via WP_Query.
